GILES, F WINDSOR, ON TARIO, CANADA, ASSIGNOR TO' DETROIT VAPOR STOVE COMPANY, OF DETROIT, MICHIGAN, 'A CORPORATION OF MICHIGAN ENAMELED ARTICLE AND METHOD OF ASSEM BLING SAME Application filed February 6, 19.30. Serial No. 426,431.

This invention relates to enameled articles and method of assembling same, and has to do particularly with a novel method of securing enamel surfaced articles to a supporting member or to each other.

In the fabricating and assembling of stove doors and like articles it has been the practice to form panel members or other articles by article in place, strains have quite frequently developed which resulted in chipping or cracking of the enameled surfaces.

It is the object of the present invention to provide a novel fastening means and method of securing the same whereby a panel or other like article may be positively secured into the desired position without in any way tending to cause any material strain upon any part of the enameled surface.

In the drawing:

Fig. 1 is a back plan view of a broiler door of the type used in connection with the standard gas stove and embodying the present invention.

Fig. 2 is a sectional view taken on line 2-2 of Fig. 1.

Fig. 3 is a fragmentary sectional view taken on line 33 of Fig. 1 and illustrating the novel method of securing one of the fastening means to the enameled insert.

Fig. 4 is a fragmentary sectional view taken on line 4t-l of Fig. 1, illustrating another method of asembling the fastening means to an enameled'insert.

It will be understood that the present invention may be embodied in a large number of different types of articles having a portion of the ornamental surface thereof coated with what is known as porcelain or glazed enamel. The broiler door, as illustrated in the drawing, is shown as being only one possible assembly in which the present invention may be embodied.

Any form of enameled article or surface which is to be attached or secured to another surface may embody the present invention and in Fig. 2, I have illustrated a broiler door construction having a [center enameled panel land an annular enameled frame 2. The base-structure to which the panels are secured may be broadlydesignated 3, and it will be obvious that, this base structure may be suitably cast or formed so as to provide depressions d and 5 for receivingthe panels.

v Suitable apertures (Sand 7 may be provided in'the base structure for receiving bolt members 8 and.9. These bolt members 8 and 9 aresecured to the back of the panel members by means of suitable straps 10 and 11.

Instead of spot welding the heads of the bolt members or the entire strap members to the panels, I preferably only weld or otherwise secure one orboth ends of the strap members torthepanels. In case the aperture for receiving the bolt member is very close to the edge of the panel, I prefer to spot weld only one end ofthestrap tothe panel as at 12'. I-Iowevenwhere there is plenty of clearance around the bolt member, it will be seen that both. ends of the strap member may be suit ably welded or otherwise secured to the panel as at 13.

It will be obvious thatthe panels so fabricated may be assembled to the supporting frame as shown in Figs. 1 and 2 and suitable nuts secured to the ends thereof and drawn up as tightas desired. As the strap members are fairly thin and welded only at the ends, it will be obviojus that each bolt member will have considerable flexibility without placing any positive strain upon any part of the enameled panels or other member. This method of as sembly permits considerable play in fitting ofthe various parts and also makes it possible to morequickly assemble the unit as the workman need not be careful in fitting the panels or other article and drawing up the bolts.

In the normal method of assembly, I preferably weld the bolt heads to suitable strap members and then spot weld the strap membersto the back of thearticles or panels to be enameled, in themanner illustrated in the draWing.-- The entire article: is then sprayed int) ' What I claim is or coated with enamel in theusual manner a part of thesupportin'g unit'and spaced and fired so as to produce the desired 'ornafrom the panel or panels for receiving and t or mental surface. The'supportiug structure, securing for instance the base of the broiler door, is

rovided with suitable apertures for receivmg the bolts and the Surfaces of such apertures are so spaced from the strap members In testimony wher that when nuts are screwed u on the bolts-the tendencyr of the strap ,mem hers is to movecured so as to set up'a resilient action between the base member or. supporting structure and 1 the panel or other enameled articles. It will be understood that the Panel members 1 and 2:: f 1 I are preferably formed of sheet metal or other similar material. 1 a

I 1. rhe th d of'securing articles enameled surfaces tofa' supporting unit,

which consists in securing a fiatifastening strap to the back of the enameled a'rticlein 1 such a manner asto provide'relatively great a bodily movement of a portion of the'fastening strap [relative to the article; andthen securing'the fastening strap in place without placin strain directly upon the article.

2., T e method of'securing articles'having enameled surfaces; to a supporting unit,

which com "rises providing bolts secured to strap mem ers," securing the strapmember's I to the back of the articles to be coated with enamel at points spaced from theaxis of the bolts, coating the articleor articles with enamel and firing the same and then securing the bolts to the supportingunit in such a manner as to cause flexing of the strap members.

3. Fastening structure for securing enaml eledarticles to supporting members comprising a strap member welded at a IocaliZed point orpoints to the back of the article, and a bolt welded to -the strap member at a point spaced from the point or points at which the strap is secured to the back of the article.

4. Ornamental construction of the type including enameled panels and a supporting unit or units having depressions forreceivin'g the same, comprising in combination 7 a: the. bolt free of the panel.

fastening means consisting of a flat str'apand a bolt' secured thereto, said strap being welded tothe back of the panel or panels at points spaced from the bolt so as to leave the part offthe strap immediately adjacent I 5.
